如何使用 JavaScript 创建 Document 对象 [英] How to create Document objects with JavaScript

问题描述

基本上这是一个问题，应该如何构造一个 Document 对象来自javascript中动态的一串HTML?

Basically that's the question, how is one supposed to construct a Document object from a string of HTML dynamically in javascript?

推荐答案

规范中定义了两种方法，createDocument 来自 DOM Core Level 2 和 createHTMLDocument 来自 HTML5.前者创建一个 XML 文档(包括 XHTML)，后者创建一个 HTML 文档.两者都作为函数驻留在 DOMImplementation 接口上.

There are two methods defined in specifications, createDocument from DOM Core Level 2 and createHTMLDocument from HTML5. The former creates an XML document (including XHTML), the latter creates a HTML document. Both reside, as functions, on the DOMImplementation interface.

var impl    = document.implementation,
    xmlDoc  = impl.createDocument(namespaceURI, qualifiedNameStr, documentType),
    htmlDoc = impl.createHTMLDocument(title);

实际上，这些方法还很年轻，仅在最近的浏览器版本中实现.根据 http://quirksmode.org 和 MDN，以下浏览器支持createHTMLDocument:

In reality, these methods are rather young and only implemented in recent browser releases. According to http://quirksmode.org and MDN, the following browsers support createHTMLDocument:

• Chrome 4
• 歌剧 10
• 火狐 4
• Internet Explorer 9
• Safari 4

有趣的是，您可以(有点)在旧版本的 Internet Explorer 中使用 ActiveXObject 创建 HTML 文档:

Interestingly enough, you can (kind of) create a HTML document in older versions of Internet Explorer, using ActiveXObject:

var htmlDoc = new ActiveXObject("htmlfile");

生成的对象将是一个新文档，它可以像任何其他文档一样进行操作.

The resulting object will be a new document, which can be manipulated just like any other document.
